WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 249,903, dated November .22, 1881.

Application filed March 24, 1881.

To all whom it may concern:

Be it known that I, WILLIAM S. COOPER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Water-Closets, of which the following is a specification.

The main objects of this invention are to insure the proper flushing of the basin and pipes, to prevent the overiiow of the basin, and to insure a tight joint between the valves and the valveseats on the basin-outlet and overflowpipe and between the supply-pipe and basininlet. These objects I attain in the manner which I will now proceed to describe, reference being had tothe accompanying drawings, in which- Figure 1, Sheet 1, is a longitudinal section of my improved water-closet; Fig. 2, Sheet 2, al plan view of the same; Fig. 3, Sheet 3, a transverse section on the line 1 2, Fig. 2; Fig. 4, a transverse section on the line 3 4, Fig.2; Fig. 5, Sheet 4, a longitudinal section, partly in elevation, of the water-supply valve; Fig. 6, a sectional plan on the line 5 6, Fig. 5; Fig. 7, a transverse section on the line 7 8, Fig. 6; and Figs. 8, 9, and 10, detached views of parts of the closet, drawn to an enlarged scale.

A is the basin of the water-closet; B, the discharge-chamber; D, the valve for closing the basin-outlet; E, the valve for controlling` the admission of water to the basin, and F the weighted pull-rod for operating the lever Gr, whereby the valves D and E are opened and closed. This leveris connected to arock-shaft, a, having two arms, I) and c, the arm b carrying the valve D, andthe arm c being adapted .to act upon a pivoted arm, d, whereby the spindle e of the valve E is elevated in order to open said valve and permit the iiow of water into the basin. The arm d has a curved portion, df, upon which the anti-friction roller on the arm c acts, this curved portion d being so proportioned in respect to the center of the rock-shaft a that movement will be. imparted to the arm immediately upon the commencement of the opening movement of the valve D, so that water will ow .through thebasin as soon as the valve D beginsto open.

The valve E is peculiarly constructed, (as described hereinafter,) in order that it will close (Model.) Patented in England September 25, 1879.

slowly, so that water will continue to flow intothe basin A for some time after the valve D is closed and the support of the arm d removed from the valve-stem e, a supply of water being thus allowed to accumulate in the basin, in order lo flush the soil-pipe when the valve D is again opened. In order to prevent this supply of water from rising in the basin A to such a height as to overflow the top of the same, I arrange at one side of the basin an overflow 6o chamber, J, divided by partitions ffinto thrce compartments, y, g', and g2, the compartments g g containing oats h and t', respectively, and the compartment g2 communicating through a passage, j, with the discharge-chamber B of the closet. The lower end of the passagej is closed by a valve, L', the rod of which is connected to the short arm of a lever, lc', the lon g arm of which carries the float h.

The compartment g communicates through k,7o a passage, m, with the basin A, so that when the water rises in the basin to a pointabove@ this passage the compartment g will be iilled and the water will flow over the partitions j' into the compartments g and g2, and the float h will be raised so as to open the valve 7c and permit the surplus water to escape into the discharge-chamber B. When the supply is cut oft' the water will gradually be drained from y the compartment g through'th`ep`a's'sagev n, and 8o as the float falls the valve lc will be raised and the passage j closed, the weightofthelloat tending to keep the valve firmly pressed against its seat, and thus prevent the leakage of gases between the two, the water which accumulates 8 5 in the passage j after the closing ofthe valve k 'being also of assistance in sealing the pipe against the passage of gas. v

rIlhe water-supply valve E is similar in general construction and operation to that shown 9o in my Patent No. 132,523, dated October 29, 1872, having a grooved plunger, p, with loosely-ttin g ring q, which during the downward movement ot' the plunger bears rmly against the upper flange ot' the same, and during the 95 upward movement of the plunger rests: on the lower flange, in which are formed Aopenings,as shown in Fig. 6. When the plunger is down the valve s rests on the seat s' and the passage of water to the basin A is prevented, roo

but when the rod e is elevated by the arm d the valve sis raised and water passes through the chest E and pipe E to the said basin. As the plunger p rises with the valve s,any water which may be above said plunger passes a round the ring q and through the openings in the lower tlange of the plunger; but the instant the plunger commences to descend under the influence of the spring s2, so as to close the valve s, the ring (1 is forced rmly against the upper flange, and the descent of the plunger is retarded by the partial vacuum form ed above the same, the only relief for this partial vacuum being the gradual inlet of water to the space above the plunger through thepassages l t t and chamber t2, the rapidity of the tlow I Y I I A being governed by the adjustment of' the setscrew t3. It will thus be seen that the closing of the valve s is gradual, in order to etfect the above-mentioned flow ot' water into the basin after the valve D of the same has been closed. It occasionally happens,however,that the supply of water is cut o' oris insuicient to properly flush the basin (hiring the time that the plunger p occupies in descending 5 hence I make provision for closing the relief-passage of the valve and holding the plunger in its elevated position until the basin has received a proper supply of water. The device which I employ for this purpose is a valve, w, Fig. 6, adapted to close the end of the passage t and acted upon by aplunger, w',the latter being connected by means of the system of levers and rods shown in Fig. 1 to the oat 'i in the compartment g( of the overilow-chamber J of the basin. When said lloat is downthat is to say, as long as the compartment g is empty-the valve w will be closed and the ilow of water through the passage t into the space above the plunger p will be prevented, so that said plunger cannot descend, and in consequence the valve s will be held open until such time as there is a ilow of water into the basin A sufficient to till the compartment g of the overflowchamber, raise the float t, and withdraw the plunger w', so as to permit the opening of the valve w andthe passage of water to the space above the valve-plunger p.

'lhe valve D ofthe basin has a rubber packing-ring, w, and the seat for this valve, and also that for the valve k, consists of a rubber ring, y, the inner edges of said rings c' and y being recessed in order to form flanges z, gradually reduced to a thin edge, so that they will accommodate themselves to foreign matters introduced between the valve and seat and prevent leakage due to the presence of said foreign matters.

To one side of the casing of the dischargechamber B of' the closet is attached a tube,P, which may be connected by a suitable system of pipes with any adjacent Ventilating-flue. The cap Q of this tube has a socket adapted for the reception of a ball at the end of the arm d, thus formin ga pivot for said arm, the ball being retained in the socket by means of a screw-plug, R.

The end ot the water-supply pipe E which enters the projection S on the basin A is threaded, and to the end of this threaded projection is adapted a collar, T, packing W being interposed between this collar and a nut, Y, on the pipe E', so that on screwing up said nut the packing will be compressed and expanded between the pipe and the interior of the projection S, thereby forming a tight joint without the use ofthe usual cements.

In carrying out my invention the float and the valve controlled thereby may be used in connection with other automatic valve-controllingdevicesthantheseshown. Forinstance,the valve fw might be employed to cut oli' the low of air through a passage to an expansion device connected with the supply-valve, said passage having, ot' course, a regulating valve or screw for a purpose similar to that ofthe screw shown in applieants valve.

I am aware that it has been proposed to connect the su pply-valve of a water-closet with a iloat in an overtlow-chamber, so that the valve would be directly opened and closed by the movements ofthe float; but my invention differs from these, in that the float in the over- 4tio w-chamber has no direct connection with the supply-valve and does not ai'ect the opening of the same or directly control its closing, being simply to regulate the action ot` the devices whereby the valve is closed.

I claim as my invention- 1. The combination of the basin of a watercloset, the supply-valve, devices for automatically controlling the closing of the same, an overflow-chamber, J, a float arranged in said overflow-chamber, and a valve operated by said oat and adapted to govern the operation of said automatic controlling devices, as set forth.
